Ben charmed the crowed by geeking out and taking a picture of the audience, saying, "I've never done this before, it’s kind of nerdy. It’s just not going to happen again, it’s kind of a cool moment for me."

As the most recent actor to embody Batman, Ben spoke about the honor with reverence, calling it "one of the most iconic characters of contemporary [times]," and saying, "I’m deeply honored and thrilled to get a chance to do it. Thank you for giving me the opportunity."

The "Justice League — Part One" footage shown to the crowd was very well-received, focusing on Ben's Batman recruiting the various members of the squad.

You'll have to wait until November 17, 2017, for "Justice League — Part One."
